    I am trying to preserve as much of my battery as possible. I checked the battery usage on my phone for the plastic few days and it shows "Display" at 55% of my battery. Is there a way to lower that number?

    Is it better to leave on auto-brightness or to put it at 1setting?

    Turn off auto brightness and turn your screen to a reasonable number. Play with it, you'll find something you're happy with. Mine is is 28% and it's usable in sunlight (99% of the time, and when it's not, I have an app with a slider to adjust it). If you click my username and hit view more posts by niceguysfinishlast, you can see my posts about battery life, and how to extend it. For example, today was a bad day for me, but would probably be considered a good day for a lot of people here, based on what I read in their posts: [​IMG]

    I wasnt able to edit this post.

    What program works good to underclock/overclock the D2G?

    Also; I have changed my display settings and it still uses 55% of my battery. Everything else is only 5-8%.

    I have on application that is always running; LOOKOUT Security. I enjoy this program but I wonder if this may be a cause of why my battery dies fast..

    I am going to charge my battery now (fully) then see how long it takes before it dies with minimum usage.

    Here's a list I compiled. The items do not apply to all phones:

    Here's my tips:

    1. (Doesn’t apply to all phones) Go to settings/wireless & networks/mobile networks/Enable always-on data. Uncheck always on data. Your phone will still receive email, text, & phone calls as before as well as internet usage but your battery will last a lot longer.

    2. Emails: I don't know what email app you use, but try this. It saves battery power and in some cases emails arrive quicker. This scheme will have you using only the Gmail app on the phone for all email accounts whether they are pop3 accounts or Gmail. Go to the Google Gmail inbox on your computer and log into the Gmail account. On the top right of the screen is an option called Settings. In there is an option to have the Gmail program poll your regular, non-Gmail accounts. Provide the email address and the password. The Google Gmail program will then poll your other accounts on a frequency from 1-5 minutes and push the email immediately to your phone. The polling frequency is determined by each account's activity - more emails = faster polling. It will always be no less frequent than every five minutes. This saves battery power because on the android OS pop3 accounts are polled at a frequency of 1-30 minutes and that really eats battery. Because the phone goes and checks those accounts for mail whether there is mail there or not.

    3. If you are using Live Wall Papers, stop!

    4. Use wifi any time it is available. It uses a lot less power than 3G and it is much faster.

    5. If there are widgets that automatically update (facebook, weather, etc.) change their update frequency in their settings menu. Set them to 30mins or 1 hour.

    6. Oh, almost forgot, get the extended battery from Verizon.

    7. Turn off the GPS unless you are actually using it. There are some background apps that can burn a lot of power via a live gps.

    8. The Power Control Widget is a good tool for easily turning on and off some of these features (gps, wifi, screen brightness, etc.).

    9. From the home screen do the following: menu/settings/About Phone/Battery Use. This graph will show the 10 biggest power users on the phone. It should always be Screen as the top user and the android os, android system, phone standby and phone idle should be the other top users. If there is an app listed you should determine if it’s an app you actually use a lot or do you have a rogue app that needs to be uninstalled.

    10. Get Screebl. It will turn your phone off anytime you are not actively using it.

    11. If you have either a task killer or an anti-virus app installed, you should uninstall.

    12. Go to data>system>and delete batterystats.bin after you've charged your phone to 100%. This helps with battery meter accuracy.


    13. D2G - go in to settings, wireless and networks, mobile network and change the network type from global to CDMA only. The d2g is locked out from using the local GSM networks in the US. You don't need global radio turned on in the US just overseas.


    Also, you do understand that the 55% represents 55% of the amount of battery that has been consumed. If your battery meter shows you're down to 80%, then the screen has been 55% of the 20% drop. If you get that percentage to go down, the others will go up.

    Go into Settings > Wireless & Networks > Mobile Networks > Network Mode > and turn off the default setting of Global and turn on CDMA. This assumes you are in the US.

    I did that. Do I leave roaming for home only or auto?

    Edit;I put it on auto.

    Step 12 I can't figure out how to get to that file..

    thanks for this. i had a d1 which i loved. upgraded to d2g. not exactly a newbie with this stuff, but at this point, to do testing, i have swithced back to my d1. I am not a heavy user, but I have every radio on, bt, wfi, gps. I have about 10 min of call a day, 10 texts, use touchdown with activesync to get emails. I don't reply on the phone, but do check it when away from my desk. my d1 normally goes 24 hours before running out.

    I have my d2g just sitting with wifi on. rooted. setcpu set to max of 1ghz. have bt, gps off. wifi will check emails of course, but i don't turn the screen on. i do have enable data to on however. phone lasts maybe 8 hours just sitting on my desk. un acceptable. . shouldn't i get more than 8 hrs without it doing anythng. will try to turn off data, but thought this would prevent me from getting updates and email.

    would really like to keep this d2g as i love the speed, no lags, and global.

    maybe i have a bad phone/battery? thanks for the help, btw, not comfortable putting new rom on it.
